Binomial System

Lesson 1 Assignment Questions Describe the scientific system by which positions be classified, in a report of up to 500 words. In this report, vertebral column *the signifi dirty dogce of the binomial system *why common references of whole workss should not be used to in good order identify make ups. The scientific system to classify and naming plants ar controlled and coordinated by botanist passim the world. The system of classification in plants is to classify them in groups with similar characteristics. Then continue to sort out and sub-group until you pitch one type of plant in each group.The main level of division in plants ar as follows workss are divide into PHYLA (singular phylum) Phyla can be divided into DIVISIONS Divisions are divided into CLASSES Classes are divided into ORDERS Orders are divided into FAMILIES Families are divided into GENERA (singular genus) GENERA are divided into SPECIES Species are sometimes divided into VARIETIES The apprehension of t he binomial system was introduced by Carolus Linnalus (1707-1778) in 1753 for f disappointing plants. The system gives each plant a name which is made up of two parts.The first part is called the generic name (or genus) and always starts with a capital. The turn part is the specific name (or epithet) and always comes after the generic name. The specific name always starts with lower case, unless it is name after a person or place. The reason common names should not be used is that some common names are given to more than one plant creating mental confusion when communication about plants. Using botanical names allow identification worldwide. Common names can verify from one country to the next.Answer each of the following briefly. A. What are the major divisions found in the plant kingdom? The major divisions found in the plant kingdom is Phyla, Division, Classes, orders, Families, Genera, Species and Varieties. B. List the basal differences amongst angiosperms and gymnosperms. The basic difference is that angiosperms are a visoring, seed plant produce seeds within a fruit, while the gymnosperms are naked seed bearing. The gymnosperms have seeds that are not enclosed by an ovary of fruit. C. Define the meaning of the termsFamily A taxonomic category of related organisms ranking below an order and above a genus. A family usually consists of several genera. Genus A taxonomic category ranking below a family and above a species and loosely consisting of a group of species exhibiting similar characteristics. In taxonomic nomenclature the genus name is used, either alone or followed by a Latin adjective or epithet, to form the name of a species. Species a. A unsounded category of taxonomic classification, ranking below a genus or subgenus and consisting of related organisms capable of interbreeding. b.An organism belong to such a category, represented in binomial nomenclature by an uncapitalised Latin adjective or noun following a capitalized genus name, as i n Ananas comosus, the pineapple, and Equus caballus, the horse. Subspecies A taxonomic atom of a species consisting of an interbreeding, usually geographically isolated population of organisms. Variety A taxonomic subdivision of a species consisting of an interbreeding, usually geographically isolated population of organisms. Cultivar A race or variety of a plant that has been created or selected intentionally and maintained through cultivation.D. Give the scientific names of 10 assorted plant species not mentioned elsewhere to date in this course. For each, indicate which family they belong to, which name is the genus, which is the species and (if applicable) which is the variety or cultivar. take a shitSyzygium australecultivar Family MyrataceaeGenusSyzygiumSpecies S. australe haveViola hederaceacultivar Family ViolaceaeGenusViolaSpecies V. hederacea NameHardenbergia violaceacultivar Family FabaceaeGenusHardenbergiaSpecies H. violacea NameAcacia vertillata Family MimosaceaeGen usAcaciaSpecies A. verticillataNameBulbine bulbosa Family LiliaceaeGenusBulbineSpecies B. bulbosa NamePultenaea dentata Family FabaceaeGenusPultenaeaSpecies P. dentata NameDichelachne rara Family PoaeceaeGenusDichelachneSpecies D. rara NameDiuris orientis Family OrchidaceaeGenusDiurisSpecies D. orientis NameLeptospermum scoparium Family MyrataceaeGenusLeptospermumSpecies L. scoparium NameWahlenbergia gracilenta Family CampanulaceaeGenusWahlenbergiaSpecies W. gracilenta 3. What is the horticultural significance of juvenility, maturity and senescence in the developmental cycle of a plant.The horticultural significant of juvenility, maturity and senescence in the developmental cycle of a plant is each stops allows different advantages of the plant. The ability for juvenile stage to be influence allows propagators to vegetatively propagate cuttings longer, while to reduce this stage allows flower and fruit growers to reduce their production costs and an earlier crop or return on invest ment. Because at this stage it has its most rapid rate of suppuration and has the ability to initiate adventitious roots readily, this is rock-bottom or lost as the plant matures.Maturity is significant for those wanting to see the results of their breeding programs or a harvest from the plants e. g. seeds and fruits. A plant is considered mature when it has the potentially capacity to reproduce. Reproduction from cuttings at this stage is reduced or the plant has no longer got the ability to form adventitious roots. Senescence is referred to the process involving the declension of the plant or its organs prior to death. To be able to control or delay this stage allows for a longer harvest time e. g. fruit and flowers. . Answer each of the following questions briefly. A. Describe the social system of the basic plant cell. Explain the function of the different cell organelles. The basic plant cell anatomical structure is made many layers which primary consist of three components being the middle lamellum, primary cell protect and secondary cell wall. There are many cell organelles Nucleus stores the genetic component (chromosomes) of the crabbed cell. Plastids are collective terms for organelles that carry pigments. Ribosomes are responsible for the synthesis of proteins.Mitochondria are thither to break down the complex carbohydrates and sugars into usable forms for the plant. Golgi Body transports chemical substances in and out of the cell. Endoplasmic Reticulum is the bond amidst the nucleus and the cytoplasm of the plant cell. Vacuoles are used for storage and help to regulate turgor squelch of the plant cell. Peroxisomes is to assist chloroplasts in undergoing photorespiration process. They also contain certain oxidative enzymes. B. Define the term Plant Tissue. Describe the characteristics and basic role of tissue found in flowering plants.Plant Tissue is the references to a collective function of large tracts of cells with similar structure. Pl ant tissues come in two basic types Meristematic tissues and immutable tissue. The meristematic basic role is to actively divide and differentiate into various cell types. After the Meristematic cells have divide they develop into Permanent tissue. Permanent tissue can be classified into simple or complex. C. pose and chase the cross section of a leaf to show epidermis, xylem, phloem, stomata and parenchyma. See attachD. Draw and label a cell diagram to show all parts you can remember without referring to your notes. See Attached 5. Answer the following question briefly. A. State the internal differences between monocotyledons and dicotyledons. There are numerous differences between monocotyledons and dicotyledons. Monocotyledons Dicotyledons A large number of vascular bundles A limited umber of vascular bundles The vascular bundles are scattered in the The vascular bundles are arranged in a ring Parenchyma tissue. Between the cerebral mantle and pith there is no There is a clear distinguish between the corted Distinction. And the pith No secondary thickening Secondary thickening can occur No annual rings are formed Due to secondary thickening annual rings are formed No cambium occurs between the xylem and Cambium occurs between the xylem and the The phloem. Phloem. B. How can strengthening tissue establish in monocotyledons in order for perennial growth to occur? The stem strengthening occurs by the many vascular bundles being scattered, rather than in a ring, with support for the bundles being surrounded by extensive fibres.
